Overview
The SFH620A-2X017T is a single-channel phototransistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an infrared LED and NPN phototransistor in a surface-mount 4-SMD package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current of 60 mA. The device provides an isolation voltage of 5300 Vrms with a typical forward voltage of 1.25 V. Current transfer ratio ranges from 63% to 200% at 10 mA input. Operating temperature spans -55°C to +100°C.
Feature Summary
- Provides galvanic isolation between input and output circuits using optical transmission.
- Designed for AC and DC input signal applications with transistor output configuration.
- Supports high insulation voltage requirements for safety-critical circuit separation.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical isolation between system components
Procurement Notes
Verify the specific suffix X017T against official Vishay documentation to confirm the exact reel packaging and tape specifications. Ensure the component matches the required surface mount footprint and pinout configuration for your PCB design. Cross-reference the datasheet revision date to validate the electrical characteristics listed in your design specifications.
Selection Notes
Select this component when high isolation voltage and surface mount compatibility are required for single-channel signal isolation. Consider the current transfer ratio range and saturation voltage for driving load requirements. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This part belongs to the SFH620 series of Vishay optocouplers, which are designed for general-purpose isolation applications. The series includes various packages and CTR options to suit different board space and performance needs. This specific model utilizes a compact SMD form factor suitable for automated assembly processes.
Replacement Considerations
Check Vishay's official substitution guide for equivalent parts within the SFH620 family or other Vishay optocouplers with matching CTR and voltage ratings. Ensure any substitute maintains the same 4-SMD package dimensions and pin configuration for direct replacement.
